GEORGE WORKMAN, OF ROCHESTER, NEW YORK.

Letters Patent N 98,137, dated December 21, 1869.

IMPROVEMENT IN HARROVVS.

The Schedule referred 'to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, Gnome Wommsx, of the cityof Rochester, county of Monroe, and State of New York, have invented acertain new and useful Improvement in Harrows; and I do hereby declarethat the following is a full and exact desqriptionthere of, referencebeing had to the accompanying drawings,

' making part of this specification, in whichtion of the strap-hinges,and the draughtbar and con- ,nections, the whole forming an arrangementby which.

the bars are easily connected, and the team may be attached at eitherend.

In the drawings- A A indicate the bars, and

B B, the strap-hinges.

The bars are of ordinary-form, and bear teeth, a a, which, however,instead .of being set in sockets or mortises, cut -in the v bars, aresctin sockets at the side of the same, formed by cutting angular notches inthe sides, and fitting thereto iron caps, b b, which form the completesocket. Thus, the teeth stand an- ,gling to the direction of motionwhich is most effeclive in breaking up'the soil. By thus applying theteeth, the bars are much stronger, and can be'reduced in size, the teethcan be more expeditiously and easily audremoved, and they are much moreefl'eclive in use.

' The hinges B B are made in the form of straps, having hinge-joints dd, of. any 'ordinary form, between thebars.

' 0n the under side of these straps are formed rightangled logs orflanges f j, which receive the bars A' A between, and hold them inplace; and on top ,is

formed aseries of hooks, g g, turning inward, as shown.

These hooks are provided at both ends of the harrow, and with themconnects a series of chains 11 h, attached to a draught-bar, D.

On the opposite or outer side of the draught-bar, areattached slackchains k k, having a ring, I, at the centre, and also a straightconnection rod, m, at the same point, but'attaching at each end to thechains back of the centre.

In ordinary work, the whifiletree may be connected with ring I; butwhen-necessary, it can be attached to the rod in, by which means theharrow is allowed to play laterally either-side of the centre, or out ofline with the team. This is frequently desirable, for instance, inworking on a hillside or around stones. This is one-0f the novelfeatures of my invention.

The two outside bars A A, on each side of the bar row, are attached to asingle strap-hinge, B, by which means the outside bars are steadied andprevented from turning. I Y

The employment of the hooks g g, formed upon the hinges, allows thedraught-barD to be connected at either end of the harrow; and theattachmentof the chains h h to the hooks, in a seriesfrom one side tothe other of the harrow, produces an equal-draw upon all parts, withoutthe sway and irregular action that occur where a single chain attachesto the centre, asin the old style.

The strap-hinges, with the flanges for the. attachment of thewoodeu'bars, and witli the hooks, for the connection of the draught-chains,"'lbelieve to be a novelty.

What I claim as my invention, is- The arrangement of the hinges B 'thflanges f f and hooks g g, the draught-bar D with chains h h andattachments k k l m, andthe teeth-attachments b b, the

whole operating in the manner and for the purpose specified.

In witness whereof, I have hereunto signed mynamel in the presence oftwo subscribing witnesses;
